<h1>Building Microservices with Node.js</h1>
<p>Microservices architecture has become a popular approach for building scalable applications. Let&#39;s explore how to implement it using Node.js.</p>
<h2>Architecture Overview</h2>
<ul>
<li>Service Discovery</li>
<li>API Gateway</li>
<li>Message Queues</li>
<li>Containerization</li>
</ul>
<h2>Implementation Example</h2>
<pre><code class="language-javascript">// Example of a microservice using Express
const express = require(&quot;express&quot;);
const app = express();

app.get(&quot;/api/users&quot;, async (req, res) =&gt; {
  try {
    const users = await userService.getAllUsers();
    res.json(users);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

// Service registration
const serviceRegistry = {
  register: (service) =&gt; {
    // Implementation
  },
};
</code></pre>
<h2>Best Practices</h2>
<ol>
<li>Use containerization</li>
<li>Implement circuit breakers</li>
<li>Handle service discovery</li>
<li>Monitor service health</li>
</ol>
